New England Patriots head coach Bill Belichick said he isn't concerned about Washington's Robert Griffin III learning from Tom Brady as the two teams hold joint practices this week. "I don't really care about that," Belichick said.

On Friday, Griffin said he hoped he would get a chance to sit down with Brady during the joint practices and "pick his brain." Griffin added that since the two are competing quarterbacks, he doesn't expect the three-time Super Bowl winner to give him any groundbreaking secrets.

Belichick isn't focused on whether Brady will be a mentor to Griffin.

"I don't really care about that," Belichick said.

Griffin is coming off of a 2013 season that saw him throw for 3,203 yards and 16 touchdowns in 13 games. Brady threw for 4,343 yards and 25 touchdowns in 16 games for New England last season.
